If you dont need your defective led strip i would be willing to buy it from u ?

Or do yourself a custom battery pack i live in the uk and have done this battery pack using a standard 7.2v nicad racing pack and a male connector all avalable from hobbystores heres some picks:

(It Runs The VB For hours its only a 1800Mah so more Mah would give you a longer running time)

Its an easy option and one less wire wile playing

Hope it helps
